Why is iron extracted from haematite, instead of iron pyrites?

The reason is pyrite is exothermic .it can cause hazard in mines. It is more economical to extract iron from others minerals. pyrite is geologically unstable and will turn into sulfurous minerals and viable ores, so it is best left for future mines. Pyrite is only suitable for making sulfuric acid or jewellary.

Rcovery of gold in pyritic ores - Mine Engineer.Com

The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to remove this iron coating and then make the fine particles susceptible to cyanide leaching. To my knowledge, this has never been attempted. Generally speaking, cyanide leaching of low grade pyritic ores is

How to Separate Gold from Pyrite - 911 Metallurgist

28/10/2016  “Upon the ordinary auriferous sulphide of iron, or arsenical pyrites, the solution of potassium cyanide acts readily, not by dissolving the sulphuret, but by attacking the gold upon its exposed edges, and eating its way into the cubes by a slow advance, dissolving out the gold as it goes. An examination with the microscope of the pyrites after the gold has been removed, suggests the method of the operation. A sample of very rich pyrites

How Iron Pyrite is Formed Actforlibraries.org

Iron pyrite is a fairly common mineral, and is mined or extracted globally for its many industrial uses, such as extraction of the sulphur for sulphur dioxide or sulphuric acid, and also as an ore for iron. It oxidises readily, making it easy to extract the component minerals, but care must be taken as this also makes it quite combustible. In the late 19th Century a newspaper story in England ...
